Alkaline phosphatase activity (APA) is an indicator of phosphorus status in marine plants. We examined APA in the symbiotic dinoflagellate Symbiodinium bermudense, which occurs with the sea anemone Aiptasia pallida. We have developed an assay for APA that serves as a biological indicator of inorganic phosphate (Pi) exposure in coral reef environments and phosphorus deficiency in zooxanthellae. ...

The present work attempts to carry out preliminary phytochemical screening, detailed pharmacognostic study and physicochemical evaluation of leaf of Crotalaria pallida. Crotalaria pallida Aiton. is a plant with vast medicinal properties. The plant has been traditionally used for the treatment of swelling of joints , fever , vermifuge, skin diseases and also The plant and its parts are reported ...

N -nitroso compounds, such as N -nitrosodiethylamine (NDEA), can be formed by the reaction of secundary amines with nitrosating agents, and are suspected to be involved in tumors in humans. NDEA has been considered a weak carcinogen in genotoxic assays probably due to the inefficient nitrosamine activation system that is used and/or to the efficient repair system. In this work, we evaluated the...

Plant-parasitic nematodes (PPN) need to be adapted to survive in the absence of a suitable host or in hostile environmental conditions. Various forms of developmental arrest including hatching inhibition and dauer stages are used by PPN in order to survive these conditions and spread to other areas. Potato cyst nematodes (PCN) (Globodera pallida and G. rostochiensis) are frequently in an anhydr...

This paper provides an overview of the Neurigona species found in Iran. During our studies northern Iran four genus Róndani, 1856 have been collected, three which for first time Iran: helva Negrobov & Tsurikov, 1990, pallida (Fallén, 1823) and pseudolongipes Negrobov, 1987. One species, persiana Pollet Kazerani sp. n., proved new to science is described here. An identification key males five kn...

This paper studies connections between the preprojective modules over the path algebra of a finite connected quiver without oriented cycles, the (+)-admissible sequences of vertices, and the Weyl group. For each preprojective module, there exists a unique up to a certain equivalence shortest (+)-admissible sequence annihilating the module. A (+)-admissible sequence is the shortest sequence anni...

Isosphaera pallida is an unusual gliding, budding eubacterium recently isolated from North American hot springs. Electron micrographs of ultrathin sections revealed a cell wall atypical of eubacteria: two electrondense layers separated by an electron-transparent layer, with no evident peptidoglycan layer. Growth was not inhibited by penicillin. Cell walls were isolated from sheared cells by vel...
